BY/MWOQWTM ATTORNEY Patented May 30, 1933 Mussi PATENT ALBERT SKINNER, F WEST CHESTER, OHIO EXPANSION JOINT FOR PA'EMENTS .AND THE LIKE Application led August 20, 1930. Serial No. 476,677.

This invention relates to pavements and has special reference to expansion joints for such pavements. l u

@ne important object of the invention 1s 5 to provide an improved form of expansion joints for concrete and other like pavements.

A second important obj ect of the invention is to provide a novel composition and arrangement of matter for such a joint.

With the above and other objects in view v, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing, like characters of reference indicate like parts in the several views, and

Figure 1 is a plane view of a section of pavement employing this expansion joint.

Figure 2 is an enlarged detail section on the line 2-2 of Figure 1.

Due to the presence of corn-borers much of the corn stalks raised by farmers is `destroyed but such stalks contain a long and elastic bre Which has been found by me to be especially valuable for use as a binder in asphaltic compositions for expansion strips designed to be laid between sections of concrete and other like pavements. Accordingly I combine .approximately 65% of corn stalk bre with approximately 25%Yof asphalt and form the sam-e into strips from one-quarter to one inch thick and up to thirty-six inches Wide and ten feet long. The faces of these strips are impregnated With approximately 10% of burlap Waste or ravellings so that the tendency of these faces to stick to other material and to stick together is prevented. Thus there is provided a body 10 formed of approximately 65 parts ofcorn stalk fibre and approximately 25 parts of asphalt and faced on both sides With a composition containing approximately 65% corn stalk fibre,

approximately 10% of burlap Waste and approximately 25% of asphalt.

In order to provide for holding the strip in position between sections 11 of pavement,

the strip faces are provided With staggered holes 12 into Which the paving material enters during the construction of the pavement.

There has thus been provided a novel come position for and construction of expansion strip for pavements.

Having thus described the invention,A What is claimed is l. An expansion strip for pavements including plastic material7 a binder of corn stalk libres, and facing material consisting of burlap Waste impregnating the faces of the strip.

2. An expansion strip for pavements including a mixture of asphalt and corn stalk fibres and having its faces impregnated with burlap Waste.

3. An expansion strip for pavements including a mixture of approximately 25 parts of asphalt With approximately 65 parts of corn stalk fibres and having its faces impregnated With approximately 10 parts of burlap Waste.

4. An expansion strip for pavements including a mixture of approximately 25 parts of asphalt with approximately 65 parts of 75 corn stalk fibres and having its faces impregnated With approximately 10 parts of burlap Waste, said faces having holes therein extending entirely through the facing material and into the body of the strip.
